Are breathy-voiced stops (like [dʱ]) only breathy-voiced during the closure, with the vowel being completely modal-voiced, or do they make the vowel begin breathy-voiced, the way an aspirated stop causes the vowel to begin voiceless?
Put more visually:
-- = Voiceless
// = Modal-voiced
~~ = Breathy-voiced
| = Release
Voiced stops are: [////|////////]
Tenuis stops are: [----|////////]
Aspirated stops are: [----|---/////]
So, are breathy-voiced stops [~~~~|////////] or [~~~~|~~~/////]?
